Treatment of drinking water residuals: comparing sedimentation and dissolved air flotation performance with optimal cation ratios

Spent filter backwash water (SFBW) and clarifier sludge generally comprise the majority of the waste residual volume generated and in relative terms, these can be collectively referred to as combined filter backwash water (CFBW). CFBW is essentially a low-solids wastewater with metal hydroxide flocs...
